Abstract
Here are provided rainfall intensity output means adapted to output rainfall intensity R as a value equivalent to a linear function of altitude H: R(H)=aH+b, and processing means adapted to identify parameters a and b in the above estimate equation by regression analysis using a measurement value obtained by rainfall vertical distribution. This invention provides thereby method and system for estimation of rainfall distribution based on rainfall spatial distribution in mountainous area.
